Needs a more recent openocd than is currently available in openwrt/packages:

opkg update
wget https://kevinmehall.net/tmp/openocd_d3c2679bcb8e8ba25e7b6e443b39f57474afc099-2_ramips_24kec.ipk -O /tmp/openocd.ipk
opkg install /tmp/openocd.ipk
rm /tmp/openocd.ipk

In another terminal:

    echo "STAGING_DIR needs to be set to your cross toolchain path";
    exit 1

Fractal Components

A code generation platform for distributed embedded systems.

Most of the code in an embedded system deals with IO, both with sensors and actuators, as well as communicating with a PC, phone, or server. Typically the domain logic implementing the unique behavior that the developer actually cares about is a small portion of the code, but ends up intertwined with all the IO, making it hard to introspect and port between platforms.

Fractal is about breaking the IO into reusable chunks, called components, with structured interfaces defined by state machines, and automatically generating code for them to communicate with each other, whether they're on the same physical hardware or across a network. By simplifying IO, developers can focus on the domain logic unique to their application.

Code in multiple languages can be mixed and matched, so developers can pick the right language for each task -- Rust and C for size and speed, JS or Lua for familiarity, ease of prototyping, and existing netw

Setup

1. Install OpenOCD. You need version >= 0.8.0.

• This version is not in Ubuntu 14.04, but the packages from Ubuntu Utopic work fine there
• brew install open-ocd looks to be 0.8.0

1. Save the openocd script below as tessel-busblaster.cfg.

2. Plug the JTAG cable into the Bus Blaster's adapter board and the Tessel. Pin one is towards the USB port; the cable goes over the center of the board.

3. Run
